晚熟哈密瓜膜下滴灌栽培技术及病虫害防治

通过对伊吾县淖毛湖镇晚熟哈密瓜1～6]膜下滴灌栽培技术及病虫害防治的研究与应用,采用(1)滴灌系统首部设计选型:水源首部采用离心式过滤及网式过滤.施肥罐选择:根据面积大小选用,一般33.33 hm2应选100 L的施肥罐,机井用潜水泵,其流量与扬程均与滴灌系统设计流量和设计水头基本一致;(2)滴灌系统灌水量平均250 m3/667m2,全生育期滴水9次,节水率65.28;;(3)滴施追肥2～3次;(4)膜上行距40～50 cm,株距45～50 cm,株数1 000株/667m2,土地利用率提高25;～30;;(5)对主要病虫害进行了调查及农药筛选,提出了农药防治方法;经大面积示范推广取得显著效益.

Culture Technics of Mulch Drip Irrigation and Pest Control of Late Mature Hami Melon

Culture techniques of mulch drip irrigation and pest control of late mature Hami Melon in Naomaohu Town of Yiwu County were studied and analyzed.The final results indicated that:(1)The water source of first selected driven well for drip irrigation system was pumped from the well by centrifugal and net filtrating equipment.The selected fertilizer cagewag is that:usually the fertilizer cageway was selected for 100 L by 33.33 hm2,the submersible pump was used to pump water for irrigation,the discharge of which was roughly consistent with the designed one by drip irrigation and desighed water head;(2) Average 25 m3/667 m2 of irrigation was applied with drip irrigation system,9 times of irrigation was applied in the whole growth stage,rate of saved water was up to65.28%;(3)Drip irrigation,application and dressing fertilizer were applied 2～3 times;(4)The utilization ratio of the land was increased by 25%～30%,when the row interval on film was kept by 40～50 cm,the plant interval was maintained by 45～50 cm.Plant number per 667m2 was up to 1 000 plants.The utilization ratio of the land was increased by 25%～30%;(5)The main plant diseases and insect pests were investigated and the pesticide were selected.The control measures of pesticide were put forward and the significant beneficial results were worth being popularized in large area.
